目的:为提高特殊环境工作人员口腔防护能力,减少电离辐射对特殊环境工作人员健康的损害。方法:参考国内外关于接触辐射人员的健康调查与防护设施、设备及措施文献资料,结合目前课题组对环境工作人员基线数据及防护成果,对特殊环境工作人员口腔损伤机制与防护进行系统全面探索与研究。结果:特殊环境工作人员在受到长期低剂量慢性电离辐射作用后,机体损伤与修复能力失去平衡,出现慢性口腔损伤,其表现主要有口腔黏膜疾病、急性龋病、口干症、牙周炎等口腔疾病。通过佩戴电离辐射面罩、口罩,使用各类防护药品以及规范的防护措施,可以减少或避免电离辐射对口腔的损伤。结论:特殊环境工作人员的口腔健康影响不容忽视,深入研究特殊环境工作人员损伤机制和防护,对保障特殊环境工作人员身体健康和遂行任务的完成具有重要的意义。 OBJECTIVE: To improve the oral protection ability of special environmental workers and reduce the damage of ionizing radiation to the health of special environmental workers. Methods: With reference to the domestic and foreign literature about the health survey, protective equipment, equipment and measures of exposure to radiation personnel, and systematically exploring the oral injury mechanism and protection of special environmental workers by combining the current task force with the baseline data of environmental workers and the results of protective measures And research. Results: After being exposed to long-term low-dose chronic ionizing radiation, special environmental workers lost their balance of injury and repair and developed chronic oral lesions. The main manifestations were oral mucosal diseases, acute caries, dry mouth and periodontitis Oral disease. By wearing ionizing radiation masks, masks, using a variety of protective drugs and norms of protective measures, you can reduce or avoid ionizing radiation on the oral injury. Conclusion: The oral health effects of special environmental workers can not be ignored. Studying the damage mechanism and protection of special environmental workers in depth is of great significance for ensuring the health of special environmental workers and completing the task.
